How to fix PEPPOL-EN16931-F001
A date MUST be formatted YYYY-MM-DD.
What this rule checks
Peppol requires all dates to use ISO 8601 format (YYYY-MM-DD) without time components. The base EN16931 rules check date presence but Peppol additionally enforces strict formatting.
How to fix it
Ensure all date elements (cbc:IssueDate, cbc:DueDate, cbc:TaxPointDate, cbc:StartDate, cbc:EndDate) use the format 'YYYY-MM-DD', e.g. '2025-01-15'.
